Random BSOD

Hello,

For a while now, when i left my computer it keeps giving random BSOD's,
I am including the minidumps here:
http://speedy.sh/UmVGd/Minidump.rar

Specs:
Windows 7 home premium 64 bits
CPU : AMD A8-3870 APU with Radeon(tM) HD Graphics (4 CPU's) 3 Ghz
RAM : 12288MB RAM
GPU : Club AMD Radeon 7840 2Gb ( Total Memory 3802 mb)
2x 22inch Screen ( Both 1920x1080)
Logitech g110 Keyboard

I wonder if anyone can see what i can do about it, because it's starting to get annoying, because my pc never did this before.

Thanks for any help!
